Dave Jones's long introduction to op-amps covering the basic rules, virtual ground, common configurations and part selection; recommended to learners who found textbook treatments hard going.
First part of Dave Jones's series designing a lab power supply with op-amp voltage and current regulation; recommended as an introduction to bench supply design.
Alan Wolke's back-to-basics walkthrough of op amp circuits, recommended for understanding how the common configurations behave before building analogue stages.
Dave Jones builds a constant current dummy load from an op-amp, MOSFET and shunt resistor for testing supplies and batteries; a common starting design for DIY loads.
Alan Wolke compares split, single and virtual-ground supplies for op amps; people use it to work out how to bias inputs from a single battery.
Dave Jones builds peak detectors from a simple diode and capacitor up to precision op-amp versions; a frequent reference for envelope and pulse detection projects.
Linear Technology's tutorial on checking op-amp loop stability and phase margin in LTspice; people follow its method, then ask why their own simulations disagree.
An introduction to op-amps that builds a sensitive microphone amplifier, linked by beginners replicating the circuit for audio and sensor projects.
An Afrotechmods tutorial on using an op-amp as a comparator, including a clapper circuit, often linked when someone needs a simple threshold detector without a microcontroller.
Alan Wolke gives a gentle introduction to the BJT differential pair and how it forms an op amp input stage; people build and simulate along with it.
Adds a current limit to a cheap buck/boost module with a sense resistor and comparator; people borrow the circuit for CC/CV chargers and motor supplies.
Dave Jones works through the design of the uCurrent, cited for his comparison of three ways to generate a negative supply rail for an op-amp.
Explains amplitude modulation and builds a simple op-amp AM transmitter; the circuit is widely copied, and people often ask how its mixer stage really works.
Linked to show crossover distortion in op amps such as the LM358, usually when someone's amplifier output is unexpectedly distorted or audibly rough.
GreatScott's basics episode on op amps, routinely offered as a quick first explanation of how they are wired and how resistors set the gain.
Dave Jones explains op-amp input bias current and the offset it creates across input resistors, linked when an amplifier's output sits away from the calculated value.
An Afrotechmods explainer on peak detector circuits, repeatedly suggested to people trying to capture the maximum level of an audio or sensor signal.
Opening part of a lecture series introducing op amps and nodal analysis around them; suggested to students stuck on op-amp circuit questions.
A basic electret microphone and op amp circuit feeding an Arduino, offered as a starting point for sound triggered projects such as shot timers.
Dave Jones works through designing a constant current source, offered as inspiration and possible help for anyone building their own.
The opening of a long university lecture series on basic electronics, recommended as a dry but solid grounding in fundamentals including op amp feedback.
